Definitions

  • the present invention relates to new azo dyes, processes for their preparation and their use for dyeing and printing fiber materials, in particular of textile fiber materials.
  • the object underlying the present invention was to find dyes which are used for dyeing fiber materials containing nitrogen and hydroxyl groups, especially of cellulosic fiber materials, are good Have fastness properties and are stable at high temperatures.
  • DE-C-853,324 discloses dyes which differ from the dyes of the present invention on the one hand with regard to the substituents Y 1 and Y 2 on the triazine ring and on the other hand with regard to the terminal azo components A 1 and A 2 .
  • EP-A-0,465,420 discloses dyes which differ from the dyes of present invention with respect to a further substituent on the Distinguish the phenylene component of the monoazochromophores.
  • C 1 -C 4 alkyl for R 1 , R 2 , R 3 and R 4 for example methyl, ethyl, propyl, isopropyl, butyl, sec-butyl, tert-butyl or isobutyl, in particular methyl or ethyl, are preferred Methyl.
  • substituents for the radicals R 1 , R 2 , R 3 and R 4 as C 1 -C 4 alkyl are hydroxy, C 1 -C 4 alkoxy, halogen or sulfato.
  • the meaning sulfo generally includes the free acid form (-SO 3 H) as well as the salt form, alkali metal salts (Li, Na, K) or ammonium salts being particularly suitable.
  • Suitable C 2 -C 4 alkanoylamino for R 5 and R 6 are, for example, acetylamino or propionylamino.
  • R 1 , R 2 , R 3 and R 4 are preferably hydrogen or C 1 -C 4 alkyl, in particular hydrogen.
  • R 5 and R 6 are preferably acetylamino.
  • radicals A 1 and A 2 are preferably identical.
  • the trihalogenotriazine compound of the formula (2) is first used in about stoichiometric amounts of an aminoazo compound of the formula (3) or Formula (5) at a temperature of e.g. -5 to 20 ° C, preferably 0 to 5 ° C, um the pH by adding suitable bases, e.g. Alkali metal bases such as lithium, Sodium or potassium hydroxide or carbonate or hydrogen carbonate, neutral to acidic, is preferably kept at 2 to 7, in particular 3 to 5.
  • suitable bases e.g. Alkali metal bases such as lithium, Sodium or potassium hydroxide or carbonate or hydrogen carbonate, neutral to acidic
  • suitable bases e.g. Alkali metal bases such as lithium, Sodium or potassium hydroxide or carbonate or hydrogen carbonate, neutral to acidic
  • the aminoazo compound the formula (3) or the formula (5) is expediently approximately stoichiometric Amounts used.
  • the triazinyl dyes of the formula (8) obtainable by the processes described above also contain halogen atoms Z which, by reaction with the compound of the formula (9) or (10) at elevated temperature, preferably 70 to 100 ° C., and a neutral to slightly alkaline pH, which is, for example, 7 to 12, in particular 8 to 12, can be converted into a group Y 1 or Y 2 .
  • the compounds of the formulas (3) and (5) can be prepared in a known manner by diazotization and coupling of corresponding starting compounds are obtained, the Diazotization in a manner known per se, e.g. with a nitrite, e.g. with a Alkali metal nitrite such as sodium nitrite in a mineral acid medium, e.g. in one hydrochloric acid medium, at temperatures of for example -5 to 40 ° C and preferably at -5 to 10 ° C.
  • the coupling takes place in a manner known per se, in the case of acidic neutral to weakly alkaline pH values and temperatures of, for example, 0 to 30 ° C.
  • the azo dyes of the formula (1) are either in the form of their free acid or preferably as their salts.
  • the salts include, for example, the alkali, alkaline earth or ammonium salts or Organic amine salts. Examples include sodium, lithium, Potassium or ammonium salts or the salt of mono-, di- or triethanolamine called.
  • Another object of the present invention is the use of the azo dyes of the formula (1) for dyeing or printing nitrogen-containing and in particular fiber materials containing hydroxyl groups.
  • the azo dyes of the formula (1) according to the invention are therefore suitable for dyeing and Printing nitrogenous or in particular cellulosic fiber materials, preferably of textile fiber materials, of silk, wool or synthetic polyamides, and preferably from the cellulosic fibers, such as rayon, cotton or Hemp.
  • direct dyes C.I. direct dyes
  • Textile fiber materials made from mixed fibers, e.g. made of wool / cotton, Polyamide / cotton, polyacrylic / cotton or in particular polyester / cotton mixed fibers by single bath dyeing and in the presence of dyes for the other types of fibers are dyed.
  • the textile fiber materials can be in a wide variety of processing states are present, e.g. as fiber, yarn, woven or knitted fabric.
  • Level dyeings in yellow shades with good general fastness properties are obtained good rub, wet, wet rub, sweat and light fastness. If necessary, can the wet fastness properties, in particular the wash fastness, of the direct dyeings obtained and prints significantly improved by post-treatment with so-called fixatives.
  • the dyes of the formula (1) according to the invention are good with other dyes, especially disperse dyes can be combined.
  • the dyes according to the invention have sufficient high-temperature stability and can thus be among the Dyeing conditions for polyester fibers, i.e. at temperatures in the range of about 100 to 150 ° C, preferably from 110 to 130 ° C, from an aqueous liquor and at a pH from 4 to 7.5, preferably 5 to 7, color.
  • Parts and percentages refer to weight unless otherwise stated. Parts by weight and Volumes are related to each other in the same way as kilograms and liters. The Temperatures are given in degrees Celsius.
  • Example 1 173 parts of 3-aminobenzenesulfonic acid are stirred in 500 parts of water / ice mixture and 128 parts of concentrated hydrochloric acid. A solution of 70.5 parts of sodium nitrite in 200 parts of water is then added dropwise at 30 ° C. in the course of 30 minutes. After the diazotization, the excess nitrite is destroyed with sulfamic acid.
  • Examples 2 to 4 The procedure is as described in the illustrative example, but instead of 33.4 parts of the compound of the formula (101), an equimolar amount of a compound of the formula is used and instead of 2.75 parts of 2-aminoethanol, an equimolar amount of a compound of the formula HY where A, R and Y have the meanings given in Table 1 below, the dyes shown in Table 1 are of the general formula obtained in which A, Y and R have the meanings given in Table 1, and which dye cotton in yellow shades.
